Editing Geography Markup Language (section)

=== ISO 19136 ===
''' ISO 19136 ''' Geographic information – Geography Markup Language, is a [[List of ISO standards|standard]] from the family [[International Organization for Standardization|ISO]] – of the standards for geographic information (ISO 191xx). It resulted from unification of the [[Open Geospatial Consortium]] definitions and Geography Markup Language (GML) with the ISO-191xx standards.

Earlier versions of GML were not ISO conformal (GML 1, GML 2) with GML version 3.1.1. ISO conformity means in particular that GML is now also an implementation of [[ISO 19107]].

The Geography Markup Language (GML) is an XML encoding in compliance with [[ISO 19118]] for the transport and storage of geographic information modelled according to the conceptual modelling framework used in the [[ISO 19100-series]] and including both the spatial and nonspatial properties of geographic features. This specification defines the [[XML]] Schema syntax, mechanisms, and conventions that:
* Provide an open, vendor-neutral framework for the definition of geospatial application schemas and objects;
* Allow profiles that support proper subsets of GML framework descriptive capabilities;
* Support the description of geospatial application schemas for specialized domains and information communities;
* Enable the creation and maintenance of linked geographic application schemas and datasets;
* Support the storage and transport of application schemas and data sets;
* Increase the ability of organizations to share geographic application schemas and the information they describe.
